Duties of Stadtwerke Norderney GmbH are to safely and reliably provide nearly 6.000 inhabitants of the island and additional over 50.000 guests (tourists) with power, gas, local heating and water. Stadtwerke Norderney GmbH is the local network provider for all these services with its own infrastructure.

The company is 100% owned by the city of Norderney and has nearly 40 employees.
The island of Norderney is located in the North Sea within the world heritage of “Wattenmeer” at the north border of Germany and is one of the seven East Frisian islands. It has an area of 26,3 square kilometres. Nearly half of the island is directly part of the world heritage “Wattenmeer” and not used by mankind.
